TO ALL' 'WHOM IT vCONCLRN: A

Be it known that I, G. K. DEABBORN, of South Boston,zin the county of Suiolk, and State of Massachu. setts, have invented an Improved Window Frame; and I do hereby declare that the following is a full and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marlied thereon. i l i Y y The nature of `my invention consists in making a window frame in such a. manner that the sashes may be easily removed when it is desirable to do so.

To enable others skilled in the art to make and -use my invention; I will proceed to describe its/ construc tion and use.

4 Drawings. Figurel is an elevation of my improved frame, with sashes'. Figure 3 is an isometric view of one side of the frame. y v Figure 2 is an elevation of the movable part of the stop-bead.

vFigure 4 is a horizontal section of the frame.

Figure 5 is a vertical section through the stop-bead.

' Figure 6 is a vertical section through .the parting-bead.

A represents a window frame,'made generally as represented in the drawings, andl is in allrespects like those in common use, except that a part-of one of the parting-beads and a part of one of the stop-beads are removable. C is the stop-bead, E is the partng-bead,'B B are sashes hung. in the-usual Way. In'ig. 3 the frame is shownwith the movable part of the stop and parting-beads removed. E (iig. 6) shows the movable part of the parting-bead, which rests upon a spring, S, and is held in position by the bevelled end of the iiXcd pai-tE of the parting-bead. C is the xed part of the stop-bend, beveilled,1 as shown, so ns to hold the movable part D D. D (g.'2) represent the movable parts of thcstop-bead.V These two parts are hinged together, and'have, at or near their junction, the latch L.- In figs. 1 and 5 4this part of the stop-bead is represented in position, the latch L holding against the metallic slip M, (tig.

To use my invention, take hold of the latch L, and bearing down and pulling upon it at the same time, the parts D D of the stop-bead will slip out of position, and leave the lower sash B free to be taken out. Now, to remove thc upper sash, rst slide it to the lower part of the frame; Vtake hold of the'movable part E of the parting-bead, press it down until its -upper end is f free to slip out by the bevelled end of the parting-bead E,

and theupper sash B can be removed. To replace the sash, reverse the operation.

Having thus described my invention, I will now proceed to set forth my claim.

What I claim as my invention, and desire to secure by Letters /Patent of the United States, is-

1. The movable parts DD] of the stop-bead, when combined and arranged substantially as set -forth.

2. The arrangement and construction of the parting-bead E E,`ma,dc substantially as and for the purpose set forth.
